The Brazilian has been the undisputed number one at the club since arriving from Roma.
Becker's new deal was announced by the club website on Wednesday, while he spoke about the agreement from their training camp in Evian.
Asked about his trust in the club, he responded: "That's the mindset. I trust the club, I trust everyone here.
"I believe the club trusts me as well to keep doing my work and keep doing my best for the team.
"As an individual, I will give 100 per cent to make this club win more trophies in the seasons coming.
"This season is really important for us. The last one was quite tricky with a lot of things that happened in our lives but I think this made ourselves more hungry for what comes in front of us.
"I have really good expectations for the season and I will do everything that is in my hands to achieve our goals."
